Git commands for branching, committing, merging, rebasing, and squashing. Use when developer needs to create branches, commit changes, merge or rebase branches, or squash commits.

Configure and maintain the Arcana skillset for a project. Init does full onboarding (install external skills + scan codebase), audit checks everything is in place, skill-up analyzes completed tasks and proposes improvements. Use when onboarding Arcana to a new project, checking configuration, or after completing a task cycle. Triggers on "arc:project init", "arc:project audit", "arc:project skill-up", "arc:project adr", "init arcana", "setup arcana", "scan project", "audit skills", "improve skills", "what can we improve", "create ADR", "document decision".

Git commands for branching, committing, merging, pushing, rebasing, and squashing. Use when developer needs to create branches, commit changes, push, merge or rebase branches, or squash commits.

GitHub commands for issues, PRs, code reviews, and shipping. Use when developer needs to create issues, create/update PRs, address review comments, or ship experimental changes. Use when developer says "create issue", "open PR", "review comments", "resolve feedback", or "ship changes".

Feature implementation workflow. Use when developer wants to implement a feature or fix - creates branch, plans, and implements. Use when developer says "implement issue", "work on issue

Interactive skill creator and refiner. Use when developer wants to create a new skill, build a skill, scaffold a skill, refine or improve an existing skill, or says "new skill". Walks through use case definition, structure planning, SKILL.md generation, and validation.

GitHub commands for issues, PRs, code reviews, and shipping. Use when developer needs to create issues, fetch issue context (title, description, comments), create/update PRs, address review comments, or ship experimental changes. Also use when another skill or agent needs ticket context — invoke issue fetch. Requires gh CLI.

Manage Acceptance Criteria — validate quality, enrich with implicit scenarios, update from feedback, and verify code satisfies requirements. Use when working with AC files in Given/When/Then format. Triggers on "validate AC", "enrich AC", "update AC", "verify AC", "check acceptance criteria", "add edge cases to AC", "does code match AC", "/arc:ac validate", "/arc:ac enrich", "/arc:ac update", "/arc:ac verify".

Write production code and manage code reviews. Implements from plan and AC with atomic commits. Review-request creates a PR, review-resolve handles review feedback. Use when implementing a task, writing feature code, creating PRs, or resolving review comments. Triggers on "/arc:code", "implement code", "write code for task", "code task", "continue implementation", "create PR", "open pull request", "resolve review", "handle PR comments".

Orchestrator — full implementation cycle from requirements to PR. Runs skills in the correct order with feedback loops. Handles single tickets, all tickets from a PRD, or bug fixes. Use when implementing a feature end-to-end, running the full development cycle for a ticket, or fixing a bug. Triggers on "arc:implement", "implement task", "implement ticket", "implement feature", "full cycle", "implement issue", "work on ticket", "fix bug", "fix issue".

Read-only investigation of a task. Scans codebase, reads ticket from tracker, produces an implementation plan. Does not modify any files. Use when estimating a task, preparing for implementation, or answering "what will this task affect?". Triggers on "arc:plan", "plan task", "analyze task", "what does this task affect", "estimate task", "investigate ticket".

Create and update Product Requirements Documents with Acceptance Criteria. PRD lives in the repository as source of truth. AC written in Given/When/Then format. Use when starting a new feature, creating requirements, writing AC scenarios, or updating existing requirements. Triggers on "arc:prd create", "arc:prd update", "create PRD", "new feature", "write requirements", "update PRD", "requirements changed".

Write, run, review, and audit tests driven by Acceptance Criteria. Tests are born from requirements, not from code. Use when writing tests from AC scenarios, running test suites, reviewing test quality, or auditing with mutation testing. Triggers on "/arc:test", "write tests", "run tests", "test from AC", "mutation testing", "audit test quality", "are tests good enough", "review tests".

Create install.yml manifest for packages installable via spm. Supports skills, agents, hooks, and rules. Use when developer wants to create an install manifest, or says "new install", "create install.yml".

Create install.yml manifest for packages installable via spm. Supports skills, agents, hooks, and rules. Use when developer wants to create an install manifest, or says "new install", "create install.yml".

Interactive skill creator and refiner. Use when developer wants to create a new skill, build a skill, scaffold a skill, refine or improve an existing skill, or says "new skill". Walks through use case definition, structure planning, SKILL.md generation, and validation.
